Evaluation of Ship Manoeuvres in Port by Using Fuzzy Fine Kinney Method

Abstract

Ports are the connection points between the sea and the land in the maritime industry, have an important role in world trade. Ports host many ships each day. The characteristics of the ships that can manoeuvre within the port limits are determined depending on the technical structure of the ports and the environmental conditions of the ports' location. The characteristics of the ships such as their type, length, width, draft, and tonnage are important factors that determine the port's limitations. If these restrictions are not followed, it is inevitable for marine accidents to happen within the port area, which can lead to severe consequences such as deaths and injuries, material damage, environmental pollution, and even disasters. Risk analysis studies are carried out in order to prevent possible accidents at the ports and to determine the perils that may occur. When the studies in this field are examined, it is determined that different risk analysis methods are utilized. By using these analysis methods, the dangers sourced from ship manoeuvring that may occur within the port limits are tried to be analysed. The purpose of this study is to create a risk analysis model to be used in the ship manoeuvres and to determine which ships are suitable for manoeuvring in a port and under which environmental conditions ship can manoeuvre. Fuzzy Fine-Kinney method was chosen as the main risk analysis methodology for this study, which has not been used in the related literature. In the study, a full mission ship's bridge simulator was used in created scenarios by taking various environmental conditions into account and coming alongside manoeuvres were carried out by masters with a pre-determined ship on a pier at a port in Istanbul. After the end of each manoeuvre, surveys were filled out and assessments were made by masters that are considered experts in the maritime domain. According to results obtained from the risk analysis method applied in the study, it was determined which ships with which characteristics are suitable for manoeuvring and under which environmental conditions.

“…It is an easy to use and numerical analysis method. It consists of the combination of three parameters: probability, exposure, and consequence, and a result is obtained by multiplying the scale values (seven for probability and six for both exposure and consequence parameters) of the three parameters numerically (Kuleshov et al 2021 ; Çınar et al 2021 ; Derse 2021 ). According to the result, actions (i.e., control measures) are put on the agenda (Gul et al 2021b ).…”
